Introduction
3 Precautions for use
This chapter covers restrictions and requirements the user should consider when using the product.
zWhen conducting the insulation resistance measurement or the dielectric strength test, be sure to
separate the connection between the motor and the driver.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected
may result in damage to the product.
zNote on connecting a power supply whose positive terminal is grounded
The USB communication connector (CN3) of the driver is not electrically insulated. When grounding the positive
terminal of the power supply, do not connect any equipment (PC, etc.) whose negative terminal is grounded. Doing
so may cause the driver and these equipment to short, damaging both. When connecting, do not ground equipment.
zStoring data in non-volatile memory
Do not turn o the main power supply while writing the data to the non-volatile memory, and also do not turn o for
5 seconds after the completion of writing the data. Doing so may abort writing the data and cause an alarm of the
EEPROM error to generate. The non-volatile memory can be rewritten approximately 100,000 times.
zNoise elimination measures
Refer to p.52 for the noise elimination measures.
zRegeneration
When a large load inertia is operated at a high speed, the power supply voltage may increase by the regenerative
energy generated, causing an alarm of overvoltage to generate. This may result in damage to the driver, so reconsider
the operating condition so as not to generate the regenerative voltage.

may cause damage to the driver.
•Connect the connectors securely. Insecure connections may cause malfunction or damage to the
driver.
•When disconnecting the connector, pull out while pressing the latches on the connector.
•When turning on the main power supply again or connecting/disconnecting the connector, turn
o the main power supply and wait for the PWR/ALM LED to turn o.
•Separate an I/O signal cable at least 100 mm (3.94 in.) from inductance loads such as
electromagnetic relays, and wire so that it is not in parallel with power supply cables and
connection cables.
•Do not wire the power supply cable of the driver in the same cable duct with other power lines or
connection cables.
•If the connection cable or power supply cable generates an undesirable amount of noise
depending on the installation and wiring, shield the cable or install a ferrite core.
•Up to three pieces of cables can be used to connect between a motor and a driver. Keep 10 m
(32.8 ft.) or less for the wiring distance between the motor and the driver.
•Keep 10 m (32.8 ft.) or less for the total wiring distance of the RS-485 communication cable. To
extend more than 10 m (32.8 ft.) causes the driver to be aected easily by electrical noise.
